What are the 3 main functions of blood? |
Transport life sustaining nutrients and O2 from the intestines, and lungs to body cells. Also, transports hormones , and protects against diseases. It also helps your body contain a constant body temp. |
Nutrients |

|
What are the 3 parts to a cell?
|
Erthrocytes Leukocytes Thrombocytes |
|
|
|
What is the main function of the Eythrocytes?
|
Responsible for the exchange of co2 and o2
|
red blood cells
|
|
|
What is the main function of the leukocytes?
|
Can move against blood flow, and leave the blood to fight infection in tissue
|
white blood cells |
|
|
What is the main function of the Thrombocytes?
|
When a broken blood vessel is met, the platelets release thromboplastins that triggers reaction resulting in a clot
|
Cut
|
|
|
What are the 3 parts to a Leukocytes?
|
Lymphocytes Monocytes Granulcytes |
White blood cell
|
|
|
What is the main function of the lymphocytes?
|
Are very important in the immune responses of an organism- types T+B
|
Immune
|
|
|
What is the main function of the Monocytes?
|
For ingesting bacteria, waste, and dead cells by phagocytosis
|
Ingesting
|
|
|
What is the function of Plasma in blood?
|
The fluid part of blood. It contains many different dissolved ions, and organic and inorganic molecules.
|
|
|
|
What blood type is considered universal donor?
|
0
|
|
|
|
What blood type is considered the universal receiver?
|
AB
|
|
|
|
Can A+ type blood receive blood from a person with B+ blood? and why?
|
No, because the A+ receiver has B antibodies that fights anything that has any antigens with B
|
|
|
|
What is a Antigen?
|
Substances that when detected as foreign to an organism stimulates the formation of specific antibodies which attack it.
|
Flags
|
|
|
What is a antibody?
|
Proteins in the blood and body fluids which recognize and attack specific antigens.
|
|
|
|
How do blood clots form?
|
When a blood vessel is met, the platelets release thromboplastin that triggers a set of reactions leading to the formation of a clot. A sticky network of proteins called fibrin forms over the injury.
|
Thrombocytes
|
|
|
What is the difference between open/closed circulatory?
|
Open: Blood out from the heart, and eaves to go into the body cells then back into the vessels then into the heart again Closed: Blood out from the hearts, and never leaves the vessels |
|
|
|
Name the 5 different
|
Arteries Arterioles Capillaries Venules Veins |
|
|
|
What is the function of the arteries (arterioles)? and structure
|
Carry blood away from the heart. When blood leaves the heart, heading towards the body, or towards the lungs it travels through large vessels. These start to split off into smaller arterioles
|
|
|
|
What is the function and structure of Capillaries? |
Capillaries are only single cell thick, allowing the exchange of gases, nutrients, waste, etc.
|
All through the body
|
|
|
What is the function and structure of veins?
|
They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out
|
|
|
|
Name 6 parts of the heart?
|
Aorta Arteries Arterioles Pulmonary Capillaries Venules Veins |
|
|
|
What are the 2 veins that bring deoxygenated blood?
|
Superior vena cava Inferior vena cava |
|
|
|
What are the 2 veins that bring oxygenated blood?
|
Left, and right pulmonary veins
|
|
|
|
What parts of a heart pump out deoxygenated blood?
|
Left/ right pulmonary arteries |
|
|
|
What parts of the heart pump put oxygenated blood?
|
Aorta then goes into the Arteries
|
|
|
|
What is the SA node?
|
Sets pace of heart, contracts atria
|
|
|
|
What is AV node?
|
Receives signal from the SA node
|
|
|
|
What is Purkinji Fibers?
|
Receive signal from the AV node, to contract ventricles
|
|
|
|
What causes the "Lubb" sound?
|
AV valves closing as ventricles contract
|
|
|
|
What causes the "Dubb" sound?
|
Semi lunar valves closing as ventricles relax
|
|
|
|
What is the P wave in a EKG?
|
Atrial contracting
|
|
|
|
What is the QRS wave in a EKG?
|
Records ventricular contraction
|
|
|
|
What is the T wave in a EKG?
|
Signals that ventricles have recovered
|
|
|
|
How does the circulatory system keep homeostasis?
|
It has ways to keep them all within normal ranges or return them to normal ranges if they get out-of-whack.
|
|
|
|
What is systemic circulation?
|
circulation of the blood between heart and the body
|
|
|
|
What is Pulmonary circulation?
|
circulation of the blood between the heart and lungs
|
|
|
|
What is a ECG?
|
Map electrical fields within the heart, to make tracings to diagnose certain heart problems.
|
|
|
|
What does Agglutination mean? |
Agglutination is the clumping or clotting of red blood cells or bacteria. In cross matching, donor red blood cells and recipients serum or plasma dont match |
if agglutination occurs it indicates that the donor and recipients blood types are incompatible |
